As a vital component in securing a property, it’s essential that multipoint locking systems are installed to function correctly.
There are a number of potential issues with multipoint locking systems that may occur from time to time, ranging from misalignment to broken gearboxes.
As a primary UK Distributor of Winkhaus Locks, Coastal have compiled a handy troubleshooting guide for the AV2, AV3 and Thunderbolt locks, helping you to identify and resolve any problems that may occur.
Winkhaus AV2
Available in contemporary (ML120) and heritage (ML80) designs, the Winkhaus AV2 autoLock is an automatic locking system that operates as soon as the door is closed.
Anti ‘push-back’ hookbolts throw automatically when the door is shut, ensuring claw engagement and security to prevent the lock being pushed back.
Some common issues and suggested remedies for the AV2 autolock are outlined below:
| SYMPTOMS | POSSIBLE CAUSE | SUGGESTED REMEDY |
|---|---|---|
| Door closing difficulty (appearing that the hooks are firing prematurely) | Dry contacting snibs | Apply light lubricant to the latch and aperture, operating snibs and lock hook box apertures and keep contacting surface |
| Wide air gap to the lock side | Adjust the hinges to give an optimum 4mm gap between keep and lock faceplate | |
| As above with flush door | Keep strikes moving due to excessive routing | Pack beneath the strike plates |
| Stiff Key Operation | Door not latch correctly (This can be proven by temporarily holding the hooks back with a suitable tape) | Relieve pressure on the hooks by gently pulling on the door extenally or pushing internally to operate |
| Incorrect adjusted keeps (The latch is the compression point, the hook sides should not contact the keeps) | Adjust keeps accordingly | |
| Deadbolt fouling within the keep | Adjust keeps accordingly | |
| Slow key operation, allowing the hooks to contact the keeps | Relieve pressure on the hooks by gently pulling on the door externally or pushing internally to operate | |
| Unable to operate the locking system (blocked) | Hooks fouling under the keeps Door dropped or incorrectly position keeps | Attempt to lift the door leaf whilst operating the lock (see door fitting guide) |
| Excessive air gap to the lock side | Adjust the door leaf closer to the lock side (see door fitting guide) | |
| Hooks and latch not throwing | Lock drive strip fouling on routing etc | Locate and relieve cause |
Winkhaus AV3
Available in contemporary (ML3120) and heritage (ML480) designs, the Winkhaus AV3 Slam Shut Autolock is an automatic multipoint locking system with independently acting hooks.
When the door is closed, duo hookbolts are triggered by a magnetic release in the centre keep to secure the door.
Some common issues and suggested remedies for the AV3 autoLock are outlined below:
| SYMPTOMS | POSSIBLE CAUSE | SUGGESTED REMEDY |
|---|---|---|
| Door closing difficulty | Dry latch | Apply light lubricant (GLS200) to the latch, aperture and keep contacting surface |
| Stiff Key Operation | Door not latch correctly (This can be proven by temporarily holding the hooks back with a suitable tape) | Relieve pressure on the hooks by gently pulling on the door extenally or pushing internally to operate |
| Incorrect adjusted keeps (The latch is the compression point, the hook sides should not contact the keeps) | Adjust centre keeps accordingly | |
| Unable to operate the locking system (blocked) | Hooks fouling under the keeps. Door dropped or incorrectly position keeps | Attempt to lift the door leaf whilst operating the lock (see door fitting guide) |
| Excessive air gap to the lock side | Adjust the door leaf closer to the lock side (see door fitting guide) | |
| Door not latching (In secure mode) | Lock drive strip fouling on routing etc | Locate and relieve cause |
| Misaligned centre keep | Check centre lines (see fitting guides) | |
| Magnet stuck in | Check operation | |

Available in a range of designs to meet your door style (ML60R, ML66S, ML60S and ML70S) the Winkhaus Thunderbolt Lock has 5 deadbolts as standard for maximum peace of mind.
High security nickel plated deadbolts fully engage the keep and prevent the sash and frame from being forced apart.
